Westdean New Build Mastic
New-build sealant joints in Westdean need attention? We cut out the old, prepare the joints and apply the right sealant.
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
New build mastic in Westdean
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you have gaps behind new kitchen upstands and skirting joints opening in the first winter, we can help, whatever the surface.
In a village or hamlet like Westdean, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Westdean needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Mention any parking rules near the property
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Related advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved and we’ll quote.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Raise failed sealant with the developer while you are covered
- Check bath and shower seals every few months as the house settles
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
Joints and finishes in Westdean homes
Westdean is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

- Any access issues, like height or stairs

What we are called out for in Westdean
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People generally contact us when they notice something like this:
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Seaford station, the sealant around baths, showers and frames is worth checking in the first year or two.
